Configuring SDM Templates
This chapter describes how to configure the Switch Database Management (SDM) templates on the
switch. Unless otherwise noted, the term switch refers to a standalone switch and to a switch stack.
Note For complete syntax and usage information for the commands used in this chapter, see the command
reference for this release.
This chapter consists of these sections:

Understanding the SDM Templates
You can use SDM templates to configure system resources in the switch to optimize support for specific
features, depending on how the switch is used in the network. You can select a template to provide
maximum system usage for some functions; for example, use the default template to balance resources,
and use access template to obtain maximum ACL usage.
To allocate hardware resources for different usages, the switch SDM templates prioritize system
resources to optimize support for certain features. You can select SDM templates for IP Version 4 (IPv4)
to optimize these features:
• Routing—The routing template maximizes system resources for unicast routing, typically required
for a router in the center of a network.
• VLANs—The VLAN template disables routing and supports the maximum number of unicast MAC
addresses. It would typically be selected for a Layer 2 switch.
• Default—The default template gives balance to all functions.
• Access—The access template maximizes system resources for access control lists (ACLs) to
accommodate a large number of ACLs.
On the Catalyst Switch Module 3012, you can also select a dual IPv4 and IPv6 template to support a a
dual-stack environment. See the “Dual IPv4 and IPv6 SDM Templates” section on page 8-2. You must
enable a dual-stack template to configure IPv6 host or IPv6 Multicast Listener Discovery (MLD)
snooping.
